Bug Description

To reproduce:
1. Semi-maximise a window
2. Place the pointer over the window
3. Hold down the ALT key, then hold the middle button on the mouse and then drag the mouse downwards

What currently incorrectly happens:
- Nothing

What should happen:
- The window should resize vertically

Note: Performing this action (resizing a semi-maximised window using the ALT+Mouse Middle Button shortcut) should switch the window from the semi-maximised to the 'restored' state. So as soon as the user starts performing this action, the window ceases to be in the semi-maximised state.

After testing I have found that the problem only happens on the middle part of the semi-maximized window. If you for example alt+middle click on the left, right, upper or lower part of the semi-maximized window it is re-sizable.

Sorry, I can't reproduce the bug in oneiric. Alt+middle button always resizes semi-maximized windows for me. But of course, you need to click in either the left or right third of the window for it to work. The resize plugin is designed to ignore the click if it occurs in the middle third, because that's ambiguous.

I see now. Your assumption that a window should be resizable while it is maximized is incorrect. A window is and should never be resizable in the dimension in which it is maximized. You need to restore the window first using the maximize button or by dragging it to unsnap it from the maximized position.

@vanvugt; performing this action (resizing a semi-maximised window vertically) should switch the window from the semi-maximised to the 'restored' state. So as soon as the user starts performing this action, the window ceases to be in the semi-maximised state.
